Abstract
The present invention provides a method of making carboxylic acids from levulinic acid, such as succinic acid and 3-hydroxypropanoic acid, by reacting levulinic acid with an oxidant such as hydrogen peroxide under acidic or basic conditions.
Claims3
A method of preparing a carboxylic acid, comprising:
- forming a reaction mixture comprising levulinic acid, an oxidant selected from peroxides, and an acid, wherein the acid is trifluoroacetic acid, under conditions suitable to prepare the carboxylic acid, wherein the carboxylic is succinic acid, wherein the reaction mixture is free of an oxidizing metal catalyst, and
- heating the reaction mixture at a temperature of from about 30° C. to about 100° C., thereby preparing the succinic acid.
